Overview

OROS Modal is a high-performance software dedicated to structural dynamics. It allows engineers to identify the dynamic characteristics of structures through Modal Analysis (EMA/OMA) and Operating Deflection Shapes (ODS).

Complete Workflow From geometry definition to final parameter identification in a seamless environment.	Ease of Use Intuitive interface designed by and for experimentalists to minimize setup time.
High Accuracy State-of-the-art algorithms for precise damping and frequency estimation.	Native Integration Fully compatible with OROS analyzers for real-time and post-analysis sync.

Software Modules

Geometry Define your structure with nodes, lines, and surfaces.	Acquisition Setup channels, impact hammer, or shaker tests.	Processing Frequency Response Functions (FRF) and Coherence.
Identification Extract Modal Parameters: EMA, OMA, and ODS.	Validation MAC and COMAC for model validation and comparison.	Import / Export Universal file formats (UFF), Excel, and reporting.
